This series draws attention to the dramatic changes taking place in our oceans, and the innovations under way to tackle them. It is supported, in part, through a grant to theguardian.org by the David & Lucile Packard Foundation, which is dedicated to improving the lives of children, enabling the creative pursuit of science, advancing reproductive health, and conserving and restoring the earth’s natural systems.

All of the journalism is editorially independent, commissioned and produced by our Guardian journalists. You can read more about content funding on the Guardian here.

All our journalism follows GNM’s published editorial code. The Guardian is committed to open journalism, recognising that the best understanding of the world is achieved when we collaborate, share knowledge, encourage debate, welcome challenge, and harness the expertise of specialists and their communities.

The only restriction to the Guardian’s coverage is where the Packard Foundation is prohibited under US law from directly funding or earmarking funds to: (a) conduct lobbying or otherwise attempt to influence legislation; (b) influence the outcome of any specific public election or carry on any voter registration drive; or (c) to undertake activity for any purpose other than charitable, scientific, or educational, within the meaning of Internal Revenue Code Section 170(c)(2)(B). This means any communications to the public in which a view is expressed about a specific legislative proposal, and the recipients of the communications are urged through a “call to action” to contact government officials, must provide a reasoned, objective consideration of facts and issues in a full and fair manner that enables third parties to develop their own positions on any legislation that may be discussed.

Unless otherwise stated, all statements and materials, including any statements regarding specific legislation, reflect the views of the individual contributors and not those of the Packard Foundation, theguardian.org, or the Guardian.
